CO2 Fractional laser is the most advanced conceptual fractional CO2 skin peeling laser system with a wavelength of 10600nm. In addition to its fine skin-peeling effect, it can effectively penetrate the laser beam into the dermis . It is the most beneficial skin recovery system and can achieve the long-term effect of collagen remodeling as well as improvement of aged skin conditions due to exposure to light. It can be very safely applied to various types of scars compared to the existing 100% total layer skin peeling lasers (CO2 or Er: YAG). In addition, it does not require a long period of recovery or side effects. It can remodel various types of deformed scars and skin tissue very effectively.
